Dark Age of Camelot

MMORPG in which there are three races of players who during normal gameplay do not interact.

these races live in the countries (realms) of Albion, Hibernia, and Midgard. each realm has a particular set of playable units such as warriors, mages, and swordsmen.

player interaction with other online players is not necessary in order to level up. the color of an opposing unit determines its strength relative to your own character. this color code changes as your own character becomes stronger.
